Sequential Geometric Approach for Device-Free Localization with Outlier Link Rejection

Algorithm 1

Detect and reject outlier links.

(1) Get the according to 5,

(2) Get the state of links according to 6,

(3) If there are affected links,

(4)  Calculate the coordinates of the intersections,

(5)  Calculate the center of the intersections () according to 7,

(6)  Get the threshold of distance () according to 8,

(7)  Estimate the outlier state of links according to 10,

(8)  If there are outlier links (outlier state is 1),

(9)   Cluster the affected links using -means algorithm based on the distance values

            .

(10)  The links in the cluster with the larger centroid coordinate is the outlier links,

(11)   Eliminate the outlier links.
